First of all, get a PC and install Ubuntu on it My Ubuntu still 32bits cause 64bits IOMMU issue with my MB I don't explain howto install it cause of lot better howto are around on forums. Do a update, security and bug issues must closed restart

I use kernel 2.6.27-11-generic

If you plan to use svn, just skip this java 6 install step. By installing 'ant' and its tools, you will take java and javac 1.6

note you could do the same for single multicore#get, compil and install ffmpeg non multi thread#root@vmlinuz-desktop:/usr/src# svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg#root@vmlinuz-desktop:/usr/src# cd ffmpeg#root@vmlinuz-desktop:/usr/src/ffmpeg# ./configure#root@vmlinuz-desktop:/usr/src/ffmpeg# make#root@vmlinuz-desktop:/usr/src/ffmpeg# make install

Got the same issue under 8,04 (also 64bits) I add a look at the look and I have seen a message of mencoder complaining about missing libdca for dts decoding. The error was suggesting to recompile mencoder with libdca support. I tried and ... it failed due to a missing dependency ... so I recompiled again without enable libdca and the result is that it seems to be able to use it now (???)

Finally !!! Reading another post I seen somebody complaining that with the mt enabled version he had issue with some mkv if audio was set to more than 2 channels .... I tried and guess what. It does work indead. All my mkvs are playing fine now. I guess this is the price to pay for using a very early svn version of mencoder ...

Everything compiles and installs alright but the machine still doesn't have the jam to transcode 1080p on the fly. After a few minutes it runs out of buffer and starts to stutter. The machine does report that multiple threads are running using 'top -H' but it really only seems to be using 1 core. The machine sits at about 35-40% idle.

Changing the configuration on the Transcoding settings tab in PMS does result in more threads being spawned (according to 'top -H') but it does not improve the performance. In fact, the performance is about the same whether I set it for 1, 2 or 4 cores which makes me think it's only using one cores.

Anyone have any insight or tips?

Regarding the tutorial, I have a couple of suggestions (just very minor things). It might be good to do something like the following prior to installing these packages from source:
